Returning to civility, I spent some time streaming the Tatrai Quartet’s legendary Haydn cycle on Hungaroton. I focused on “The Lark” from the 1986 set Six String Quartets, Op. 64 (Hungaroton, 1986), which I also have on CD. String quartets can be a litmus test for a hi-fi system. Four string players in a room, simple recording with nowhere to hide. These Tatrai recordings sound fine with the PS Audio Stellar Strata Mk2, but came to life with the Allnic. While soundstage depth was similarly wide, depth expanded dramatically with the Allnic. The real magic was in the timbre. Closing my eyes, the realism was beyond what I’ve experienced with solid-state amplification. 

Many of my listening impressions of the RHPA-7500 were consistent for both headphone and speaker listening. One example I particularly appreciated was that turning up the volume resulted in the musical presentation becoming larger rather than just feeling louder. Not only is this phenomenon enjoyable in itself, but it is an illustration of how the Allnic is just as easy to listen to at higher levels as it is at moderate levels. And considering I was not using efficient speakers, it indicated to me modest power rating of 10-20 watts goes a long way.
